Working with Advanced Template Functions

1. Using String Functions

Function	Example	Result
repeat	repeat 3 "ab"	ababab
nospace	nospace "a b c"	abc
untitle	untitle "Hello World"	hello world
swapcase	swapcase "AbC"	aBc
shuffle	shuffle "abc"	random permutation
indent / nindent	indent 4 .	Prepend N spaces
wrap N s / wrapWith	Word wrap	Multi-line

2. Using List Functions

Function	Use
list a b c	Build list literal
first / last / rest / initial	Access ends
append . v / prepend . v	Add element
concat l1 l2	Combine lists
uniq .	Remove duplicates
sortAlpha .	Alphabetic sort
reverse .	Reverse order
has v .	Contains?
without . v	Remove element
slice . i j	Subrange
compact .	Drop empty entries

3. Using Dict Functions

Function	Use
dict "k1" v1 "k2" v2	Build map
get d "k"	Read key (returns empty if missing)
set d "k" v	Mutate in place; returns dict
unset d "k"	Remove key
hasKey d "k"	Boolean
keys d / values d	Slices
merge dst src	Shallow merge (dst wins)
mergeOverwrite dst src	Recursive merge (src wins)
pick d "k1" "k2"	Subset by keys
omit d "k1"	Inverse of pick
deepCopy d	Independent copy

4. Using Type Functions

Function	Returns
typeOf v	Reflect type (e.g. string)
kindOf v	Kind (map, slice, string, int64, bool...)
kindIs "map" v	Boolean check
typeIsLike "string" v	Substring match on type name
empty v	True for nil/0/""/empty collections
coalesce a b c	First non-empty value

5. Using Path Functions

Function	Use
base p	Last path element
dir p	Parent directory
ext p	File extension
clean p	Normalize ../
isAbs p	Absolute path?

6. Using Crypto Functions

Function	Use
genPrivateKey "rsa" 4096	RSA/DSA/ECDSA/Ed25519 PEM key
genCA "ca" 3650	Self-signed CA cert + key
genSignedCert "cn" ips dns days ca	Cert signed by CA
genSelfSignedCert "cn" ips dns days	Self-signed cert
htpasswd "user" "pass"	bcrypt htpasswd line
bcrypt "pwd"	bcrypt hash
derivePassword	Master-password-derived password

7. Using URL Functions

Function	Use
urlParse u	Dict with scheme/host/path/query
urlJoin dict	Build URL from parts
urlquery s	Query-encode

8. Using Regex Functions

Function	Use
regexMatch pat s	Boolean match
regexFind pat s	First match
regexFindAll pat s -1	All matches
regexReplaceAll pat s repl	Substitution
regexSplit pat s -1	Split into list

9. Using Sprig Functions

Category	Examples
String	upper, trim, printf, replace
Math	add, mul, div, max
Date	now, date, ago
Lists/Dicts	list, dict, merge
Crypto	sha256sum, genCA, bcrypt
UUID	uuidv4

10. Using Math Functions

Function	Result
add a b ...	Sum of integers
sub a b	Subtraction
mul a b ...	Product
div a b	Integer division
mod a b	Modulo
max a b ... / min a b ...	Bounds
floor / ceil / round	Float rounding
addf / subf / mulf / divf	Float variants
